Numbugga was settled around the same times as the nearby towns of Bega and Bemboka. The present route of the Snowy Mountains Highway follows the old route, except for a few deviations that are now roads in their own right, such as Coopers Gully Road and Garfield Road. The area used to have three schools until the mid-1970s. A hall used to stand close to the location of the current Numbugga Bushfire Brigade shed. The Numbugga Bushfire Brigade is part of the NSW RFS
